Embraer proposes GPX merger with no new shares

Digital participation requests and required documents are due by October 28, 2026; remote voting ballots are due by October 26, 2026.

Rhea-AI Filing Summary

Embraer S.A. (EMBJ) is seeking shareholder approval to merge its wholly owned subsidiary Embraer GPX Ltda. into Embraer at an extraordinary meeting on October 30, 2026, held exclusively by digital means. Management proposes an effective date of October 31, 2026, assuming corporate approvals are obtained by that date. GPX’s book net equity was R$ 10,584,362.50 as of June 30, 2026.

If approved, GPX would be extinguished and Embraer would succeed to its assets, rights and obligations. The merger would not increase Embraer’s capital stock, issue new shares or change rights attached to existing shares, because GPX is wholly owned and its net equity is already reflected in Embraer’s equity under the equity method. Management says the transaction is intended to simplify the corporate structure and reduce administrative costs; estimated total merger costs are approximately R$ 150,000.00. Shareholders are also asked to ratify Forvis Mazars Auditores Independentes as appraiser and approve its report.

equity method of accounting financial

"as a result of the application of the equity method of accounting"

An equity method of accounting is the way a company reports its financial interest in another business when it has significant influence but not full control, typically owning between about 20% and 50% of the voting stock. Instead of listing the investment at purchase cost or consolidating every line item, the investor records its proportional share of the other company’s profits or losses and adjusts the investment value for dividends or impairments, so investors see the economic impact of that stake. This matters because it changes reported earnings and asset values in a way that reflects ongoing performance—similar to showing your share of a small business’s monthly profit on your own books rather than just the amount you originally paid for your share—and helps gauge how much influence that stake has on the investor’s financial health.

book value of net equity financial

"appraisal report of the book value of GPX’s net equity"

universal successor regulatory

"as universal successor and without interruption"

remote voting ballot regulatory

"remote voting system through the submission of the respective remote voting ballots"

Golden Share regulatory

"the Golden Share is a special class share held by the Federal Government"

A golden share is a special class of stock that gives its holder the ability to block or control certain major decisions — like sales, mergers, or changes to a company’s charter — even if they own only a small percentage of the shares. It matters to investors because it can limit takeover bids, reduce the influence of ordinary shareholders, and change a company’s strategic options much like a master key that can lock or unlock key doors.

(“Protocol and Justification”), for the purpose of governing the terms and conditions applicable to the merger of GPX into Embraer (“Merger”), under the following terms and conditions: 1. Purpose 1.1. Basis of the Merger The purpose of this Protocol is to establish the basis for the Merger, pursuant to which, as of the Effective Date: 1.1.1. Embraer shall merge the entirety of GPX’s net equity, at book value, and shall succeed GPX in all of its rights and obligations; and 1.1.2 GPX shall be extinguished, and, as a result, the quotas issued by GPX shall be cancelled and extinguished, with Embraer’s capital stock remaining unchanged following the Merger, pursuant to Clause 4.3 of this Protocol and Justification. 2. Justification for the Merger 2.1. Justification The Merger is aligned with Embraer’s strategy of optimizing its corporate and business structures.

Coronel Silva Teles, 1002, Conj. 54, 5th floor, Zip Code 13024-001, enrolled with the CNPJ/MF under No. 07.326.840/0004-30, registered with the Regional Accounting Board of the State of São Paulo under CRC No. 2SP023701/O-8 (the “Appraisal Firm”), as of the reference date of June 30, 2026 (the “Reference Date”), based on the balance sheet prepared by GPX’s management for the Reference Date and for this specific purpose. According to the information contained in the Appraisal Report, the total book value of GPX’s net equity is equivalent to R$ 10,584,362.50 (ten million, five hundred and eighty-four thousand, three hundred and sixty-two reais and fifty centavos) as of the Reference Date, which is already reflected in Embraer’s balance sheet (the “Reference Balance Sheet”) as an investment. Manual and Management Proposal > Annex I – PROTOCOL AND JUSTIFICATION 25 3.2. Changes in Equity Any changes in GPX’s equity occurring between the Reference Date and the Effective Date shall be fully absorbed by Embraer and recorded directly in its financial statements. 3.3. Conflict The Appraisal Firm has represented that it has no direct or indirect interest in the companies involved in the Merger nor in the Merger itself that could prevent or affect the preparation of the Appraisal Report requested of it for purposes of the Merger. 3.4. Appraisal under Article 264 of the Brazilian Corporations Law Since GPX’s capital stock is wholly owned by Embraer, the Merger shall not result in any increase in Embraer’s capital stock or the issuance of new shares by Embraer, as described in Clause 4.3 of this Protocol and Justification, and there is, accordingly, no applicable share exchange ratio. Therefore, the Appraisal report and the other rules set forth in Article 264 of the Brazilian Corporations Law do not apply to the Merger. 4. Capital Stock 4.1. Capital Stock of GPX As of this date, GPX’s capital stock is one thousand five hundred reais (R$1,500.00), divided into one thousand five hundred (1,500) quotas, with a par value of one real (R$1.00) each, all held by Embraer, its sole quotaholder. 4.2.

Effects of the Merger Upon the completion of the Merger on the Effective Date: (i) Embraer shall absorb the entirety of GPX’s assets and liabilities; (ii) the Merger shall not result in any increase in Embraer’s capital stock, which will remain unchanged, given that the entirety of GPX’s capital stock is held by Embraer and, therefore, GPX’s net equity is already fully reflected in Embraer’s net equity as a result of the application of the equity method of accounting; (iii) there shall be no change, as a result of the Merger, in the economic or voting rights attached to Embraer’s existing shares; and (iv) the quotas representing GPX’s capital stock shall be extinguished and cancelled upon the Merger. 5. General Aspects of the Merger 5.1. Withdrawal Rights and Article 264 of the Brazilian Corporations Law Since the quotas issued by GPX are wholly held by Embraer, no withdrawal rights shall be exercisable as a result of the Merger. Likewise, the Appraisal referred to in Article 264 of the Brazilian Corporations Law is not required, insofar as there are no quotaholders of GPX other than Embraer. 5.2. Exchange Ratio Not applicable, given that: (i) Embraer is the sole quotaholder of GPX; (ii) the quotas representing GPX’s capital stock shall be extinguished and cancelled as a result of the Merger; and (iii) there shall be no increase in capital stock or issuance of new shares by Embraer as a result of the Merger.

Our work will be conducted in accordance with Technical Communiqué “CTG 2002 – Valuation Report Issued by an Accountant” and with Brazilian and international auditing standards issued by the Federal Accounting Council (CFC). These standards require the auditor to comply with relevant ethical requirements set forth in the Code of Professional Ethics and Professional Standards issued by the CFC, and to plan and perform the audit to obtain reasonable assurance that the accounting information is free from material misstatement. An audit involves performing procedures to obtain audit evidence regarding the amounts and disclosures in the accounting information. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the accounting information, whether due to fraud or error. An audit also includes evaluating the appropriateness of the accounting practices used and the reasonableness of accounting estimates made by management, as well as evaluating the presentation of the accounting information taken as a whole. Reports to be issued Upon completion of our work, we will issue the following document: • Valuation report on the accounting net equity of Embraer GPX Ltda., determined based on accounting records, for the period ended June 30, 2026. The content of the aforementioned reports will be discussed with the Company’s management prior to their final issuance. Should the Company fail to respond within five (5) days of the report being sent to it, the delivery of the reports by Forvis Mazars shall constitute acceptance of the services; conversely, a refusal to accept without valid reason shall result in the Company automatically assuming full and unrestricted responsibility for any consequences arising from non-receipt that might harm the Company, Forvis Mazars, or third parties. FEES Approach to providing professional services related to the Net Equity Valuation Report Based on the scope and premises presented in the technical proposal, our fees are detailed below: Fees In Brazilian reais - BRL Net Equity Valuation Report - Embraer GPX Ltda. 25,400.00 Total fees 25,400.00 The fees shall be paid in 2 (two) equal installments via bank payment slip, with the first installment due 30 (thirty) days after the express approval of this Instrument, and the subsequent installment(s) due on the same day of the following month(s).

Purpose of the appraisal The purpose of the appraisal of the book value of net equity, as of June 30, 2026, of Embraer GPX Ltda., is to support the merger, by Embraer S.A., of its wholly-owned subsidiary Embraer GPX Ltda. (the “Company”). Management’s responsibility for the accounting information The Company’s management is responsible for maintaining the accounting books and preparing accounting information in accordance with the accounting practices adopted in Brazil, as well as for relevant internal controls as it has determined are necessary to enable the preparation of accounting information free from material misstatement, whether due to fraud or error. A summary of the significant accounting practices adopted by the Company is described in Exhibit I to the appraisal report. Scope of work and responsibility of the independent auditor Our responsibility is to express a conclusion on the book value of the net equity of the Company, as of June 30, 2026, based on work conducted in accordance with Technical Communication CTG 2002, approved by the Federal Accounting Council (CFC), which provides for the application of examination procedures to the balance sheet for purposes of issuing an appraisal report. Accordingly, we examined the Company’s balance sheet in accordance with applicable accounting standards, which require compliance with ethical requirements by the accountant and that the work be planned and performed with the objective of obtaining reasonable assurance that the book value of net equity determined for purposes of preparing our appraisal report is free from material misstatement. The issuance of an appraisal report involves performing selected procedures to obtain evidence regarding the amounts recorded. The procedures selected depend on the accountant’s judgment, including the assessment of the risks of material misstatement of net equity, whether due to fraud or error. In making those risk assessments, the accountant considers internal controls relevant to the Company’s preparation of the balance sheet in order to plan procedures that are appropriate under the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal controls. The work also includes evaluating the appropriateness of the accounting policies used and the reasonableness of the Manual and Management Proposal 44 > Annex III – APPRAISAL REPORT accounting estimates made by management. We believe that the evidence obtained is sufficient and appropriate to provide a basis for our conclusion. Conclusion Based on the work performed, we conclude that the amount of ten million, five hundred and eightyfour thousand, three hundred and sixty-two reais and fifty cents (R$ 10,584,362.50) of the assets and liabilities shown below, as recorded in the balance sheet as of June 30, 2026 and registered in the accounting books, represents, in all material respects, the net equity of the Company, as of the reference date of June 30, 2026, appraised in accordance with the accounting practices adopted in Brazil.

Summary of the significant accounting practices adopted by the Company PRESENTATION OF THE FINANCIAL STATEMENTS The financial statements were prepared and are presented in accordance with the accounting practices adopted in Brazil, including the accounting pronouncements issued by the Accounting Pronouncements Committee (CPC), and disclose all material information relevant to the financial statements, and only such information, which are consistent with that used by management in conducting its operations. Basis of preparation The financial statements were prepared based on historical cost (except when a particular line item required a different basis) and, when applicable, were adjusted to reflect the measurement of assets and liabilities at fair value in subsequent measurement. The preparation of the financial statements requires the use of certain estimates, judgments and assumptions, which requires Management to exercise judgment in applying the Company’s accounting practices. The areas involving a higher degree of judgment or complexity, or the areas in which assumptions and estimates are significant to the preparation of the financial statements, are described in the Estimates, Judgments and Assumptions section. SIGNIFICANT ACCOUNTING PRACTICES We present below the significant accounting practices adopted in the preparation of these financial statements. 1. Functional currency The Company’s functional currency is the Real (“R$”), which is the currency of the primary economic environment in which it operates, based on the following indicators: • The currency that most influences the prices of goods and services. This is the currency in which the sale prices of its goods and services are denominated and settled; • The currency of the country whose competitive forces and regulations most influence the business; • The currency that most influences the costs of providing products or services, that is, the currency in which such costs are normally denominated and settled; • The currency in which funds from financing activities are usually generated and in which funds generated by operating activities are accumulated. Manual and Management Proposal > Annex III – APPRAISAL REPORT 47 2. Presentation currency of the financial statements In compliance with Brazilian legislation, these financial statements are presented in reais (“R$”). All balances are expressed in reais, except when otherwise indicated. These financial statements were translated into the presentation currency using the following criteria: • Assets and liabilities at the exchange rate in effect on the balance sheet date; • Comprehensive income, the statement of cash flows and the statement of value added at the average monthly exchange rate; and • Net equity items at the exchange rate in effect on the date they arose. 3. Foreign currency transactions Foreign currency transactions are translated into the functional currency using the exchange rates in effect on the transaction dates. Monetary assets and liabilities denominated and settled in foreign currencies at the balance sheet date are translated back into the functional currency at the exchange rate in effect on the date thereof. The resulting translation adjustments are recognized in profit or loss as net monetary and foreign exchange variations. 4. Cash and cash equivalents Cash and cash equivalents comprise cash on hand, bank deposits and other highly liquid investments with original maturities of up to 90 days from the date of acquisition and subject to insignificant risk of change in value. 5. Provisions, contingent assets and liabilities, legal obligations and judicial deposits Provisions are recognized taking into account the opinion of legal counsel, the nature of the claims, similarity to prior proceedings, complexity and the position taken by the courts. Whenever a loss is assessed as probable, resulting in a probable outflow of resources to settle the obligations, and when the amounts involved can be measured with sufficient reliability, a provision is recognized. Provisions for labor claims are recognized based on the historical percentage of disbursements for each claim. The provisioned amounts reflect the Company’s best estimate of the expected outflow of resources. A contingent liability is a possible obligation arising from past events, the existence of which will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not entirely within the entity’s control; or a present obligation arising from past events that is not recognized because it is not probable that an outflow of resources embodying economic benefits will be required to settle the obligation, or because the amount of the obligation cannot be measured with sufficient reliability. Legal obligations arise from tax obligations whose legality or constitutionality has been challenged, the amounts of which are recognized in full in the financial statements. Regarding environmental provisions, the Company maintains ongoing monitoring of any environmental Manual and Management Proposal > Annex III – APPRAISAL REPORT 48 impacts that its operations may cause. Where deviations are identified between the Company’s parameters and those established by applicable legislation, corrective actions are planned and measured, and a provision is recognized taking into account all amounts necessary to achieve the desired remediation. Judicial deposits, presented as other assets, are monetarily restated. The amount recorded in provisions is considered sufficient to cover the Company’s estimates of any potential losses. - Medical cost trend rate: represents the increase in the value of medical plans and is not applied on a linear basis, since companies have historically tended to take actions aimed at reducing costs, or even changing their health plan provider. - Morbidity rate (aging factor): measures the increase in the use of health plans as a result of the aging of the population. - Mortality table: the RP-2000 Generational table made available by the Society of Actuaries, which shows the mortality rate by age bracket and gender, is used. - Retirement probability: an estimate of the probability of retirement by age bracket. - Turnover rate: the T-3 Service table made available by the Society of Actuaries, which shows the average employee turnover rate by age bracket, is used. Remeasurements of the provision are recognized in other comprehensive income, net of taxes, to the extent that assumptions are updated, and in profit or loss when there is a change in the costs of the benefit plan in effect or when there are any changes to the plan’s contractual terms. Both the calculation, which uses the projected unit credit method, and the assumptions related > Annex III – APPRAISAL REPORT to this provision are reviewed annually by qualified independent actuaries. 6. Income tax and social contribution Income tax and social contribution expense comprises current and deferred income tax and social contribution. Current and deferred tax are recognized in profit or loss, except to the extent that they relate to items recognized directly in net equity or in other comprehensive income. Current and deferred income tax and social contribution are calculated based on the 15% rate, plus a 10% surtax on taxable income exceeding R$ 240 for income tax purposes, and 9% on taxable income for social contribution on net income purposes. Deferred income tax is recognized on temporary differences between the tax and accounting bases of assets and liabilities. For purposes of recognizing deferred tax assets arising from temporary differences and tax losses, the Company assesses the expectation of generating future taxable income against which such temporary differences and accumulated tax losses could be offset. Deferred tax assets and liabilities are offset when there is a legally enforceable right and the intention to settle them on a net basis upon determination of current taxes, generally relating to the same legal entity and the same tax authority. Accordingly, deferred tax assets and liabilities in different entities or in different countries are generally presented separately, and not on a net basis. This exhibit is an integral and inseparable part of the appraisal report on the book value of the net equity of the Company, as of the reference date of June 30, 2026, issued for the purpose of supporting the merger, by Embraer S.A., of its wholly-owned subsidiary Company.

Transaction protocol and justification, pursuant to Articles 224 and 225 of Law No. 6,404, of 1976 The “Protocol and Justification for the Merger of Embraer GPX Ltda. into Embraer S.A.” entered into between the management of Embraer S.A. (“Embraer” or “Company”) and of GPX Ltda. (“GPX”), on September 10, 2026, is attached as Annex I to this Management Manual (“Manual”). 2. Other agreements, contracts and preliminary agreements governing the exercise of voting rights or the transfer of shares issued by the surviving or resulting companies, filed at the company’s headquarters or to which the company’s controlling shareholder is a party Not applicable. 3. Description of the transaction, including: a. Terms and Conditions The transaction consists of the merger of GPX into the Company, with the consequent extinguishment of GPX, which shall be succeeded by the Company with respect to all of its assets, rights and obligations (the “Merger”). All of GPX’s assets and liabilities shall be absorbed by the Company. The Merger shall not result in an increase in the Company’s capital stock, which shall remain unchanged, considering that the entirety of GPX’s capital stock is held by the Company and, therefore, GPX’s net equity is already fully reflected in Embraer’s net equity as a result of the application of the equity method. For this reason, no new common shares shall be issued by the Company as a result of the Merger, and there shall be no exchange ratio whatsoever. The Merger of GPX shall be carried out based on the book value of GPX’s net equity, as reflected in its balance sheet as of the reference date of June 30, 2026, provided that any changes in net equity recorded after such reference date shall be recognized and reflected in the Company. b. Indemnification obligations i. Members of management of any of the companies involved Not applicable. ii. In the event the transaction is not consummated Not applicable. c. Comparative table of the rights, advantages and restrictions of the shares of the companies involved or resulting from the transaction, before and after the transaction There shall be no changes to the rights, advantages and restrictions of the shares issued by the Company, comparing the scenarios before and after the Merger. Not applicable with respect to GPX, which shall be extinguished and succeeded by the Company with respect to all of its assets, rights and obligations. The information contained in item 12 of Embraer’s Reference Form regarding the shares comprising its capital stock, as currently available, shall remain unchanged after the transaction. d. Any need for approval by debenture holders or other creditors Not applicable. Manual and Management Proposal 51 e. Assets and liabilities that would form each portion of the equity, in the event of a spin-off Not applicable, since this is not a spin-off. f. Intention of the resulting companies to obtain registration as a securities issuer Not applicable, since the Company already holds registration as a Category A securities issuer and GPX will be extinguished as a result of the Merger. 4. Plans for the conduct of corporate business, particularly with respect to specific corporate events intended to be carried out The Merger shall not change the conduct of the Company’s corporate business, since GPX is already a wholly-owned subsidiary of the Company. Accordingly, after the Merger, the Company shall continue to engage in the development, manufacture and sale of aircraft and aerospace materials across its various business segments, maintaining its status as a publicly held company. The Company’s corporate purpose shall also remain unchanged, and there is no other specific corporate event related to the Merger intended to be carried out. 5. Analysis of the following aspects of the transaction: a. Description of the main expected benefits, including synergies, tax benefits and strategic advantages: As a result of the Merger, the Company’s corporate structure shall be simplified, with a consequent reduction in costs for the Company, which shall no longer need to maintain a wholly-owned subsidiary. b. Costs The costs related to the Merger include the Appraisal Firm’s fees, legal fees and expenses relating to the registration of the applicable corporate acts, excluding taxes. The total amount of such costs shall be approximately one hundred and fifty thousand reais (R$ 150,000.00). c. Risk factors The Company does not foresee any risk factors related to the Merger, as it involves a whollyowned subsidiary. d. If a related-party transaction, any alternatives that could have been used to achieve the same objectives, indicating the reasons why such alternatives were rejected Not applicable, given that this is a merger of a wholly-owned subsidiary, such that no alternatives exist. e. Exchange ratio Not applicable, given that, as this is a merger of a wholly-owned subsidiary, no shares shall be issued by the Company and, consequently, no exchange ratio applies. Manual and Management Proposal > Annex IV – INFORMATION ABOUT THE MERGER 52 f. In transactions involving controlling companies, controlled companies or companies under common control i. Share exchange ratio calculated in accordance with Article 264 of Law No. 6,404, of 1976 Not applicable, given that, as this is a merger of a wholly-owned subsidiary, no shares shall be issued by the Company and, consequently, no exchange ratio applies. ii. Detailed description of the negotiation process for the exchange ratio and other terms and conditions of the transaction Not applicable, given that, as this is a merger of a wholly-owned subsidiary, no shares shall be issued by the Company and, consequently, no exchange ratio applies. iii. If the transaction was preceded, within the preceding twelve (12) months, by an acquisition of control or an acquisition of a controlling block of shares: • Comparative analysis of the exchange ratio and the price paid in the acquisition of control • Reasons justifying any differences in valuation across the different transactions Not applicable. iv. Justification of why the exchange ratio is commutative, with a description of the procedures and criteria adopted to ensure the commutative nature of the transaction or, if the exchange ratio is not commutative, details of the payment or equivalent measures adopted to ensure adequate compensation Not applicable, given that, as this is a merger of a wholly-owned subsidiary, no shares shall be issued by the Company and, consequently, no exchange ratio applies. 6. Copies of the minutes of all meetings of the board of directors, fiscal council and special committees at which the transaction was discussed, including any dissenting votes A copy of the minutes of the meetings of the board of directors held on September 10 and September 29, 2026, as well as a copy of the minutes of the meeting of the fiscal council held on September 10, 2026, are attached as Annex IV.6 to this Management Manual. 7.
